'''''Bela decussata''''' is a species of [[sea snail]], a marine [[gastropod]] [[mollusk]] in the [[Family (taxonomy)|family]] [[Mangeliidae]].<ref name="WoRMS">{{WRMS species|139214|''Bela decussata'' (Locard, 1892)||8 August 2011}}</ref>

==Taxonomy== The taxonomy of ''Bela decussata'' <small>(Couthouy, 1839)</small> has changed due to repeated reclassification. The accepted name of this species is neither a primary homonym, nor currently a secondary homonym of ''B. decussata.'' Other members of this genus such as ''Bela arctica'' have been lumped and split into different genera throughout their history of classification based on morphology. Genetic testing and subsequent phylogenetic clustering would shed light on the specifics of taxonomic relationships with finer detail.<ref>{{Cite journal |last=Merkuljev |first=Alexei V. |date=2017-02-09 |title=Taxonomic puzzle of Propebela arctica (A.
